油气田开发工业已进入特殊阶段,其典型标志是地下渗流规律越来越复杂。本文适应现代石油工业的发展需要,为解决基本渗流理论面临的问题而进行了探索性研究——提出了石油非达西渗流新的运动模式,并对该理论在油田开发中的应用作了详细研究。本文运用无因次分析法对岩芯渗流实验数据进行了研究与分析,发现石油渗流除了人们熟知的线性达西流和高速紊流外,还有3种新的运动形态(亚高速、低速及超低速流动),在无因次关系曲线上确定了各种流态相互转化的临界判据系数。从物理和力学角度进一步研究了这些特殊运动形态,结果与渗流实验完全一致。通过对5种渗流形态的分析,建立了描述石油渗流规律的统一数学模型——指数式非达西运动方程。建立的新非达西渗流模型不仅适用于常规油藏的开发,而且,可以解决低渗及裂隙等特殊油藏的开发问题。在以上理论研究的基础上,运用新的非达西渗流方程,分别建立了单相和多相流体以及复杂多孔介质(具有分形特征)中的稳定和不稳定渗流模型,形成了相对完整的新非达西渗流力学研究体系。最后,应用本文研究成果对2个油田4口生产井的矿藏资料进行了计算与分析,结果与实际符合较好。因此,本文提出的新的非达西渗流理论可以用来指导油田开发。本文通过新的非达西渗流理论及应用研究,取得 Oil and gas field development industry has entered a special phase, the typical sign of underground flow is more and more complex. This paper adapts to the needs of the development of the modern petroleum industry, and explores the problems that the basic percolation theory has to solve - puts forward a new movement mode of oil non-Darcy seepage and details the application of this theory in oilfield development the study. In this paper, we use the non-dimensional analytic method to study and analyze the experimental data of the seepage of the core, and find that besides the well known linear Darcy flow and high-speed turbulent flow, there are three new types of oil flow (sub-high speed, Ultra-low-speed flow), in the non-dimensional relationship curve to determine the various critical cross-flow conversion coefficient. These special forms of motion are further studied physically and mechanistically, and the results are in good agreement with the seepage experiment. Through the analysis of five kinds of seepage patterns, a unified mathematical model describing the law of oil seepage - exponential non-Darcy equation of motion is established. The new non-Darcy flow model established is not only applicable to the development of conventional reservoirs, but also can solve the development of special reservoirs such as low permeability and fractures. Based on the above theoretical studies, the new non-Darcy flow equations are used to establish the steady and unstable seepage models in single-phase and multi-phase fluids and complex porous media with fractal features, respectively, resulting in a relatively complete new Non Darcy seepage mechanics research system. Finally, the results of this paper are used to calculate and analyze the mineral resources of four production wells in two oilfields. The results are in good agreement with the actual data. Therefore, the new non-Darcy seepage theory proposed in this paper can be used to guide oilfield development. This article is obtained through the new non-Darcy seepage theory and applied research
